Abstract

The invention relates to a refrigerator, and provides a method for automatically opening the door of a refrigerator based on image recognition to solve the problem that the door of an existing refrigerator cannot be opened when the hands of a user are not free. The method comprises the following steps: a refrigerator is electrified, and a main control board and a human body sensor are started; a camera is started and kept in a standby state, and a service program is started and kept in a to-be-triggered state; when the human body sensor detects that a person is approaching, the camera is switched from the standby state to a normal working state, and the service program is triggered; and the service program is connected with the camera, makes the camera focus on the front of the refrigerator to acquire image information of the environment, compares the acquired image information with an image feature library, and starts a door opener to open the door of the refrigerator if the result shows that the image information matches the image feature library. The method of the invention is applicable to refrigerators with an automatic door opening function.
